Cleveland, Ohio, a corporation of Delaware Application April 20, 1939, Serial No. 269,001 15 Claims. (Cl. 255-51) This invention relatesto an apparatus for the mining of coal or similar mineral. More particularly it has to do with the pitchmining of hard coal or similar. mineral.

In my prior application, .Serial No. 153,659, filed July 14, 1937, there is disclosed and claimed an apparatus for the mining of coal or similar mineral which includes means for supporting a combined boring and expansive force inducing element assembly in a vein adjacent the breast or face of coal or similar mineral to be mined and for shifting such assembly either to any desired angular positionlor raising and lowering such assembly or moving such assembly transversely. The present invention is a modification of such means. 1

Ac'c0rdingly,'an object of the present invention is to provide a means for supporting the combined boring and expansive force inducing element assembly in a vein adjacent the breast of coal or similar mineral.-

Another object ,of, the presentinvention is to provide a means 'for shifting the combined boring and expansive force inducing element assembly to a position such that, the boring elements are in a horizontal or vertical plane which is at an angle substantially parallel with the I pitch of the floor of the vein; a v

, A further object of the prevent invention is to provide a means for raising and lowering the combined boring and expansive force inducing element assembly in its a ngularposition to any position intermediate thefioor and roof of the vein.

A still further object of the present invention is to provide a means for moving'the combined boring and expansive force, inducing element assembly transversely and to 'any' position intermediate the lateral ribs. I

Other objects and advantages willbe apparent as the invention is described in greater detail in connection with the accompanying drawings wherein:

Figure 10 is a sectional" view taken on the line Ill-10 of Figure 9.

Referring to Figures 1 and 2, the numeral I designates a housing from which protrude a series ofspaced and aligned boring elements 250, said elements being rotatably mounted within said housing. Associated with such boring elements are expansive force inducing elements on the line but since-they form no part of the present invention, they are not shown. A casing 18 encloses a gear mechanism, and a tubular member or sleeve 42 which encloses the actuating mechanism, connecting saidboring elements to said gear mechanism is interposed between the housing I and casing I8.

Asshown in Figure 1, a supporting sleeve I65 surrounds the tubular member or sleeve 42 and is secured to the transmission casing l8. Securely. mounted upon sleeve 42 and suitably 3Q spaced from the sleeve I65 isa second supporting sleeve I65 which comprises supporting brackets. I66 and 167. As the structure of these brackets is the same, only one will be described in detail. The braclce't' I66, as shown in Figures v 1: and 6, has a semicircular portion or section 1 68" which surrounds the upper half portion of the sleeve 42-and apertured' ears or lugs I69 and I 'l'll projecting from .said portion "I58. Tubes I TI, Figures 1 and 2, extend transversely through the lugs I69 and I70 and are supported in cross travel en'd brackets I IZ. It will be apparent, however, that there are also two tubes I'll which extend through the other bracket I 61 and are likewise: supported in the brackets I12;

By reference to Figures 1 and 2, it will be seen that there are a plurality of trolley wheels I13 mounted for travel along the tubes Ill, the said trolley wheelsbeing carried by the supporting brackets 165 and I161 comprising the sleeve I65. Each of the trolley wheels I1 3, Figures 6, 7, and 8, is rotatablymountedon a pin I 14 carried by a trolley bracket I 1-5. The trolley bracket I15 is provided with a plurality of slotted openings 116 which maybe movedinto'complemental relation with any one of the openings I11 in either of the lugs I89 and I18, and the bracket I15 and lug I69 or I18 locked together by means of a bolt I18. As shown in Figure 1, the rollers designated by the letters B and D are positioned so that they will straddle the top surface of the tubes (II while the rollers designated by the letters A and C are positioned so that they will bear upon the tubes I'II at an angle to the horizontal. By this arrangement the rollers Band D support the weight of the combined boring and expansive force inducing element apparatus, and the rollers A and C act to counteract the ack pressure caused by the action of the boring elements while working in the breast of coal or mineral. j

The cross travel end brackets I12, Figure 2, are rotatably mounted on end supporting brackets I19 which are movable upon each of the supporting standards 248. Figure 3, are provided with a plurality of slotted openings I88 which may be moved into complemental relation with any one of the openings I8I in the end supporting bracket I19, Figure 4, and the brackets I12 and I19, Figure 5, locked together by means of bolts I82.

The supporting standards 248, Figures 1, 2, and 5, are provided with toothed racks I83. Each of the racks I83 is in meshing engagement with a gear I84, Figures 9 and 10, carried by a shaft I85. Fixedly mounted upon the shaft I85 and suitably spaced from the gear I84 is a worm I88 which is in mesh with a worm I81 carried by a shaft I88 provided with a squared free end I88 for the reception of a suitable wrench for rotating the shaft I88 in either desired direction. The brackets I19 also carry guide wheels I88, Figure 2, which ride upon the smooth under surface of the toothed racks I83.

Referring to Figures 1 and 2, the supporting bracket I88 of the sleeve I65 carries a reversible motor I9I which rotates a pinion I92.- The pinion I92 meshes with a toothed rack I93 carried by a transversely extending tube I94 which is supported by and secured to cross travel endbrackets I12. By this mechanism the combined boring and expansive force inducing apparatus is moved back and forth transversely across the face or breast of coal or mineral.

The top ends of the supporting standards 248, Figures 1 and 2, are connected to side I beams 288 and 28I disposed adjacent the ceiling of the vein by means of brackets 282. The lower ends of the supporting standards 248 are connected to side I beams 285 and 286 of the carriage 281 by means of brackets 288. The side I beams 285 and 288 also carry brackets 289 to which are connnected the lower ends of telescopic supports 2I8 and 2H. The upper ends of each of the telescopic supports 2I8 are connected to the brackets 2I3 carried by the side I beams 288 and 2M, and the upper ends of each of the telescopic supports 2II are connected to brackets 2I2 also carried by the side I beams 288 and 28L Extending transversely between the side I beams 288 and 28I are I beam tracks 2I6 which are connected thereto by means of brackets 2I1.

The carriage 281, Figures 1 and 2, is provided with wheels 2I8 which ride along tracks 2I9 longitudinally disposed along the fioor of the vein. The wheels 2I8 are connected to the side I beams 285 and 288 by means of brackets 228 and 22I. The tracks 2I9 set in boots 222 and 223, and are fixedly secured thereto. To the sides, of each of the boots 222 and 223 are se- The brackets I12,'

cured yokes 224 to which are attached the lower ends of telescopic tubes 225. The upper ends of the telescopic tubes engage with the ceiling of the vein and are anchored thereto by means of claw shaped shoes 226. Jacks 228 are mounted on I beams 285 and 286 for moving the carriage 281 along the tracks 2I9. The tracks 2I9 are provided with means for lockingthe carriage 281 at the stopping position, such means comprising a' dog'233 carried by the "side I beams 285 and 286 which engages with a toothed rack 238 fixedly secured to the top of the tracks 2I9.

In operation of the apparatus according to the present invention, the tubular member or sleeve 42 is shifted to a position such that the boring elements will be in a horizontal plane which is at an angle substantially parallel with the pitch of the fioor of the vein. This is done by removing the bolts I82, rotating the cross travel end brackets I12 in the direction such that the proper one of the openings I8I is brought into registry with the slotted opening I88 corresponding .to the position to which the tubular member has been moved, then inserting the bolts I 82. through the registering pair of openings I8I and I88, and locking the brackets I12 and I19 in their aligned position by turning down the nut on the bolts I82.

To raise or lower the tubular member 42 so that the boring elements will be in a position intermediate the roof and floor of the vein, a wrench is placed upon the squared end I88 of the shaft I88 and such shaft rotated in the proper direction until the boring elements have been raised or lowered to the desired extent. The rotation of the shaft I88 causes the gear I84 to travel upwardly or downwardly along the toothed racks I83 through the medium of Worm I81, worm I86 and shaft I85.

To shift the tubular member 42 transversely so that the boring elements will be at a position to attack a multiple of the working breast extending from either the right or left hand lateral ribs or intermediate said ribs, the reversible motor I9I is actuated in the proper direction to effect movement of the tubular member to the right or left. The actuation of such motor causes the pinion I92 to travel along the toothed rack I93 to the right or left depending upon the direction in which the motor shaft is rotated.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
